Early XT600 models (43F/1VJ/2KF/NF/3AJ) have a narrow connecting rod with 35 mm crank pin and thrust washers; if the technically more sensible, wider connecting rod kit of the XT600K+E is to be used, this kit is mounted without the original thrust washers
XT600K+E (also fits TT600E/S/R/RE as well as XT600Z'86- and XT600'87- with 35 mm crank pin)
